The same Cyrillic character previews look fine for me on real hardware 
(Intel UHD Graphics 620) and in a virtual machine (virt-manager, spice, 
virtio video). Identifying what is different in your VM will require 
more information about the virtual hardware, and the GPU driver that is 
in use by gnome-shell.
